Closer view of the glacier in the winter A glacier cave under Mendenhall Glacier. Mendenhall Glacier (Tlingit: Áakʼw Tʼáak Sítʼ) is a glacier about 13.6 miles (21.9 km) long located in Mendenhall Valley, about 12 miles (19 km) from downtown Juneau in the southeast area of the U.S. state of Alaska.

The ice formations in the cave were formed by thawing snow which drained into the cave and froze during winter. [4] Since the entrance to the caves is open year-round, chilly winter winds blow into the cave and freeze the snow inside. In summer, a cold wind from inside the cave blows toward the entrance and prevents the formations from melting.
An ice cave is any type of natural cave (most commonly lava tubes or limestone caves) that contains significant amounts of perennial (year-round) ice. At least a portion of the cave must have a temperature below 0 °C (32 °F) all year round, and water must have traveled into the cave’s cold zone.
Apart from Alaska, around 1330 glaciers, 1175 perennial snow fields, and 35 buried-ice features have been identified. [ 2 ] [ 3 ] This is a dynamic list and may never be able to satisfy particular standards for completeness.
Ice cave history. Mount Rainier was once known for its well-developed ice cave system, the Park Service said. Those melted away due to a warming climate. Now, ice caves are seasonal and more unstable.
It is located in Vatnajökull National Park and at the glacier edge are ice caves and some geothermal features. [6] The main volume of the Jökulsá á Fjöllum river flows from the Kverkfjöll area. [7] The Volga River directly drains the Kverkjökull glacier into the Jökulsá á Fjöllum. [4]

The roof of the cave is about 10 metres high at the highest point, and the tunnels are around 15m broad at their greatest width. [12] The floor of the lowest and westernmost part of the cave, called Íshellir ("Ice Cave"), is covered in a perpetual sheeting of ice and large ice speleothems are common within the cave. [4]
